Thanks for the suggestions. My builtin price
chart has
<FONT color=#800000
size=4>#include <FONT color=#ff00ff
size=4>"C:\\program files\amibroker\afl\include\writeuponstock.afl"<FONT
size=4>;
and I tried using
<SPAN
>#include "C:\program
files\amibroker\afl\include\writeuponstock.afl", and
, Progra~1 , and neither of them worked.
<SPAN
><FONT
size=2>
<SPAN
>I am pretty sure
that I would overheat my brain once again if I tried to learn
all about WriteIf. Also,from what I read in Help, WriteIf()
would be of no use in getting ,<FONT
color=fuchsia>"BwidthPctChg",to
appear in the popup menu.
<SPAN
><FONT
size=4>
<SPAN
>Further, I found
nothing in help about modifying built-in indicators. I looked at past posts of
how to add to the builtin indicators, and none of them even mentioned the popup
menu.
<SPAN
><FONT
size=4>
<SPAN
>Does anyone have other
ideas of how to make the builtin popup menus display additional
information? Ron D

If it does not work even after
doing what graham has said below, try changing Program files to
Progra~1

<SPAN
>Johan, thanks for the
code. I made a custom version of the built-in price chart so I would
not risk harming the built-in price chart. Below, I have copied the
custom duplicate Price Chart, with your code pasted in above
the<SPAN
>
//--Indicator-End-- <SPAN
>line as you
instructed. I have also copied the error message that I get when I
click on Apply.
<SPAN
>I then clicked
on OK after viewing the error message, and this same error message is
the only thing that shows up in the indicator window. Somehow, this
added coding prevents the original portion of the built-in price window
from seeing whatever else that it needs to see.
<SPAN
>I looked in help for
WRITEUPONSTOCK but could find no reference to it.. I am
guessing that it would work if it were coded using WriteIf(
xxxxxxx). I will try to learn a little about this when I have more
time.
